IMPROVED SHEARS FOR CUTTING BOLTS.

Specitication forming part of Letters Patent No. 57,705, dated September4, 1866.

To all whom it may concern:

Beit known that I, JONES GUTHRIE, ofthe citlvr of Wilmington, county ofNew Oastle,'

and State of Delaware, have invented an Improved Tool for Cutting Bolts,Nails, or Iron Rods; and I do hereby declare the following to be anexact .description thereof, reference being had to theaccompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification, in which- Figure ltrepresents a perspective viewof the tool; Fig. 2, a sectional view; and Fig. 3 the movable knife andits connecting-plate.

A represents the long handles or parallel levers working on a pivot orjoint, B, the pivot heilig set to one side of the circular plaie C, soas to operate as an eccentric. Between the plates O is a long but curvedconnecting-plate, D, working loosely on two pins, E E, at each end oftheplate I), one pin E being attached to the circular plate O, andprojecting from it, and the other pin E projecting from the lower sideof the cutting-knife G, this knife working in a slot of the end of thetool as a guide. At the end of the tool is a short knife, J, movable bya setscrew, so that the blade or beveled edge of the knife can be takenout at an)7 time to be sharpened.

In operating the tool the handles are opened and the screw or rod to becut is placed bebetween the cutting-edges of the knives at K. Theclosing of the handles brings the knives against the rod, and it is ontwith ease 'from both sides. This tool is used to cut off the ends ofscrews close to the nuts of the runninggear of carriages. The set-screwL stops the handles or levers from closing any nearer together thannecessary, so that the edge of the movable knife G does not closeagainst the edge ofthe opposite knife J.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the parallel levers A A, the joint B, with theconnecting-plate E and movable knife G, operating against an oppositeknife, J, and the set-screw L, all constructed and arranged as hereindescribed,for the purposes set forth.

JONES GUTHRIE.
